Martian crater provides reminder of Apollo 16 mission

The Martian crater named 'Orion Crater'

During the 45th anniversary of Apollo 16‘s voyage to the Moon, NASA’s Opportunity Mars rover drove by a relatively young Martian crater, providing a connection between the two missions. The feature was informally named “Orion Crater” by the Opportunity mission team, in honor of the Apollo 16 lunar module – Orion.

Orion was the name of the Lunar Module that carried astronauts John Young and Charles Duke to and from their lunar site, on the Descartes Highlands in 1972. Orion also happens to be the name of NASA’s newest crew-rated spaceship which the space agency is developing to send crews on missions beyond-Earth orbit.

Opportunity’s Panoramic Camera (PanCam) took images of Orion Crater on April 26, 2017. The crater is about 90 feet (27 meters) wide and estimated to be no older than 10 million years.

“It turns out that Orion Crater is almost exactly the same size as Plum Crater on the Moon, which John Young and Charles Duke explored on their first of three moonwalks taken while investigating the lunar surface using their lunar rover,” said Opportunity science-team member and SpaceFlight Insider contributor Jim Rice, of the Planetary Science Institute, Tucson, Arizona.

Rice sent the Pancam mosaic image of Orion Crater to Apollo 16 Lunar Module Pilot Charles Duke, to which the Apollo astronaut responded with much enthusiasm.

“This is fantastic. What a great job! I wish I could be standing on the rim of Orion like I was standing on the rim of Plum Crater 45 years ago,” Duke said.
